Early stage malignant tumors are often accompanied by microcalcifications. X-ray-based mammography examinations are routinely used for screening and early detection due to the excellent contrast of calcified structures. However, due to the damaging nature of x-ray radiation, the use of an MR-based technique would be desirable for repeated examinations. In this work, we present initial results of quantitative-susceptibility-mapping-based (QSM) mammography-like MR-images that show robust detection of calcifications down to the resolution of the MR scan. Furthermore, the proposed method accounts for the potential presence of silicone breast implants allowing robust QSM in proximity to silicone implants for the first time.
